This document specifies safety requirements and protective/risk reduction measures, and the means for their verification, for all types and sizes of mobile elevating work platforms (MEWPs) intended for moving a person(s) along with their necessary tools and materials at an elevated work location.
This document also applies to MEWPs designed for applications requiring special access to specific work areas (formerly covered by ISO 16653-1). These MEWPs can be either self-propelled or manually propelled and are used to elevate personnel to a level at which they can place, install, or retrieve objects or material on a routine basis. To facilitate operator access to the work area, the retraction of a portion of the MEWP's work platform guardrail system(s) can be necessary.
This document is intended to serve as a guide for manufacturers, remanufacturers, engineers, and designers of MEWPs to achieve the following objectives:
— elimination or reduction of accidents and personal injuries;
— establishment of criteria for design, manufacture, remanufacture, rebuild/recondition, testing and performance; and
— establishment and understanding by manufacturers, remanufacturers, engineers, and designers of their responsibilities.
The design and manufacturing requirements of this document apply to all MEWPs manufactured on or after the effective date, but it is not applicable to rebuilt or reconditioned MEWPs.
It identifies the hazards arising from the use of MEWPs and describes methods for the elimination or reduction of these hazards.
This document is not applicable to
a) permanently installed personnel-lifting appliances serving defined levels,
b) firefighting and fire rescue appliances (see for example, EN 1777:2010),
c) unguided work cages suspended from lifting appliances (see for example, EN 1808:2015),
d) elevating operator position on rail-dependent storage and retrieval equipment (see for example, EN 528:2021),
e) tail lifts (see for example, EN1756 -1: 2001+ A1: 2008, EN 1756-2:2004+A1: 2009),

m) elevating operator positions on cranes,
n) certain requirements for insulating aerial devices on a chassis for use in live work on electrical installations. (see Note 1)
o) multi-purpose elevating platform powered industrial trucks (MPEPs) controlled by a single standup riding operator and intended to be used for manually picking and transporting small items at height. (see, for example, ISO XXXXX: 20xx),
p) powered industrial trucks used to pick and place stock or inventory.

It does not cover hazards arising from
— use in potentially explosive atmospheres,

This document specifies the safety requirements for the integration of machinery into a system. It gives requirements and recommendations for inherently safe design, safeguarding and complementary protective measures, and information for use of an integrated manufacturing system (IMS).
NOTE In the context of this document, the term system refers to an IMS which can also collaborate with other domains within the supply chain(s) of an enterprise (e.g., smart manufacturing). See also 5.2.2.
This document is not intended to cover safety aspects of individual machines and equipment that can be covered by standards specific to those machines and equipment. Therefore, it deals only with those safety aspects for the safety-relevant interconnection of the machines and components. Where
component machines of an integrated machinery system are operated separately or individually, the safety requirements of the relevant safety standards for these machines and equipment apply.
This document is also applicable when a modification of an existing IMS results in a new configuration, function, capability or location.
This document deals with the significant hazards, hazardous situations or hazardous events when used as intended and under specified conditions of misuse which are reasonably foreseeable. This document also provides requirements for IMS used in applications as following, but does not cover the hazards related to
— underground use,
— nuclear environments,
— potentially explosive environments,
— hazards due to the lifting of persons,
— use of IMS in environments with hazardous ionizing and non-ionizing radiation levels,
— when the public have access.
Emission of acoustic noise could be identified to be a significant hazard but the reduction of noise emissions is not covered in this document.

This document specifies the performance test method of electrically driven low-pressure air compressor packages, where the compression is performed by positive displacement or dynamic compression; utilising atmospheric air as the compression gas. Low-pressure air compressor packages are often referred to as “blowers”.
NOTE Throughout this document, the term ‘low-pressure compressor’ is used to describe a low-pressure air compressor (“blower”) package
Low-pressure compressors with and without means of controlling flow (control may be electrical (e.g. with a variable frequency drive) or mechanical or both) are covered.
This document applies to low-pressure compressors meeting all the following limits:
— Atmospheric inlet air pressure between 0,5 bara and 1,1 bara.
— Discharge vs Inlet pressure differential between 0,1 bar and 2,5 bar.
— Discharge vs Inlet pressure ratio between 1,1 and 3,5.
This document is not applicable to:
— positive displacement low-pressure compressors with a liquid in the compression element (such as liquid ring pumps and liquid injected low-pressure compressor of screw type)
— multi-stage low-pressure compressors other than multistage centrifugal compressors comprised of multiple, identical or very similar uncooled sections along a single shaft (repeating stages).
— single shaft, multistage centrifugal compressors are treated from the point of measurement and calculation as a single stage

This document defines the assessment of endurable longitudinal compressive forces (LCF) of a vehicle. The endurable longitudinal compressive force is a parameter depending on the vehicle design. It is used to estimate the risk of derailment as a result of being subjected to these forces, under operating conditions.
NOTE 1 As operating conditions may vary in several aspects (infrastructure, train configurations etc.), this document defines uniform assessments of endurable longitudinal compressive force per vehicle in specific operating conditions. One of these endurable longitudinal compressive forces is derived from UIC 530-2:2011, which is based on practical tests performed in ERRI-B12. Other endurable longitudinal compressive forces as the outcome of this document are central input parameters in the methodology of IRS 40421. IRS 40421 derives train and operational parameters from the outcome of this document which are vehicle parameters.
This document applies to the following types of vehicles:
— single wagons;
— permanently coupled units with side buffers and screw couplers between the vehicles;
— permanently coupled units with diagonal buffers with screw couplers between the vehicles;
— permanently coupled units with a bar coupler between the vehicles;
— articulated units with three 2-axle bogies;
— wagons with 3-axle bogies; low-floor wagons with eight or more axles (e.g. rolling road wagon);
— vehicles with central couplers;
— on-track machines (OTM) as defined in EN 14033-1:2017.
NOTE 2 This document defines the acceptance process to be followed by vehicles that are operated in a way that high longitudinal compressive forces may occur in the trains due to their operational environment (e.g. train composition, braking regime, track layout). Therefore, vehicles among the previous list which are not subjected to high longitudinal compressive forces may not need to fulfil this document.
The following vehicles are not in the scope of this document:
— articulated wagons with more than three 2-axle bogies;
— locomotives and passenger rolling stocks;
— vehicles that are only operated in passenger trains.
Acceptance criteria and test conditions as well as conditions for simulation and test dispensation are defined in this document.
This document applies principally to vehicles which operate without restrictions on standard gauge tracks in Europe (1 435 mm).
NOTE 3 The influence on railway systems using other gauges is not sufficiently understood to extend the scope of this document to gauges other than standard.
NOTE 4 For wagons with central couplers, a need for assessment of derailment risk due to Longitudinal Forces on other gauges (1 524 mm, 1 600 mm, 1 668 mm) has been expressed. The influence on railway systems using other gauges is not sufficiently understood. This document only introduces some notions to assess it independently from the gauge.
